About This Skill
What it does
This skill provides static type checking for Python code. It analyzes your codebase to find potential type errors without actually running the program, improving code quality and reducing runtime bugs. The tool helps ensure that variables have the expected types, preventing unexpected behavior and making code easier to maintain.
When to use it
- Before submitting a pull request: Ensure new or modified Python code adheres to defined type annotations and doesn't introduce type errors.
- During refactoring: Verify that changes to function signatures or data structures don’t break existing type contracts.
- As part of continuous integration: Automate type checking as a gatekeeper in your development pipeline.
- When working on large Python projects: Improve code maintainability and reduce debugging time by proactively identifying type-related issues.
Key capabilities
- Static type analysis
- Type error detection
- Python type hinting support
- Code quality improvement
Example prompts
- "Run mypy on this Python file: [file path]"
- "Check the types in this code snippet: [code snippet]"
- "Analyze this project for potential type errors."
Tips & gotchas
- Requires Python and
mypyto be installed. Ensure your environment is properly configured before using the skill.
